When it comes to health, there are some powerful molecules that remain relatively unknown by the general population. Alpha-lipoic acid is just one of these important molecules, acting as an antioxidant and playing an integral role in cellular energy metabolism. There are two forms of alpha-lipoic acid: r-lipoic acid and s-lipoic acid. R-lipoic acid is the biologically-active form the human body prefers. The Na refers to the sodium salt that stabilizes the R-lipoic acid. The sodium makes it less likely to bind, keeping each molecule separate and more readily available […]
